Two questions. Your exact compression size.
Most compression brands size by shoe size alone — which is how you end up with socks that roll, pinch, or sit in a drawer. Graduated compression only works when it fits. Sixty seconds, no email required.

Why sizing is the whole game
Graduated compression isn't a uniform squeeze. A true 20-30 mmHg sock is engineered to be strongest at the ankle and to ease off gradually up the calf — that's what the two numbers describe, measured in millimeters of mercury. The gradient is the product, and it's knit into the sock at specific circumferences. It only lands where it was designed to land if the sock actually matches your leg.
That's why clinical fitters measure the ankle and calf before handing anyone a compression garment — and why brands that size by shoe size alone get it wrong so often. Feet and calves don't scale together. Too small, and the sock pinches and rolls at the cuff. Too big, and the gradient the sock was built around never lines up with your leg. Shoe size is only a starting estimate. Size from your ankle measurement — that is where the 20-30 mmHg is delivered — and check that your calf falls inside the same size's range. A soft tape measure is what settles it.
| Size | U.S. shoe size | Ankle circumference | Calf circumference |
|---|---|---|---|
| M | Women 5-7.5 | 7-8.25 in | 11-13.5 in |
| L | Women 8-10.5 · Men 7-9.5 | 8.25-9.25 in | 13.5-15 in |
| XL | Women 11+ · Men 10-12.5 | 9.25-11 in | 15-16.5 in |
| Size by your ankle measurement — that is where the 20-30 mmHg is delivered. If your calf falls outside the range for that size, you need a wide-calf garment rather than a different size in this style: email info@ovenahealth.com and we'll help. Don't size down, and don't size up to make a calf fit. | |||

Know your numbers
Most "compression" sold online is 15-20 mmHg — or carries no rating at all, which means nobody verified that a gradient even exists. Ovena is true graduated 20-30 mmHg: knit to spec, checked at the factory, from a company that makes clinical wound-care products for a living.
| Level | What it is | Where you'll find it |
|---|---|---|
| 8-15 mmHg | Barely-there squeeze | Sheer and fashion hosiery |
| 15-20 mmHg | Everyday light | Most lifestyle "compression" brands |
| 20-30 mmHg | Medical grade — the 20-30 mmHg level clinicians commonly recommend | Ovena lives here |
| 30-40 mmHg | Firm — clinician-directed | Fitted in clinical settings |
From a wound-care company, not a lifestyle brand
Ovena was founded by David Chahine, MD, and built its name in clinical wound care — dressings made in ISO 13485-certified facilities, where specs get verified rather than assumed. The compression line is held to that same standard: true graduated 20-30 mmHg, knit to spec and checked at the factory.
The design brief was simple: real medical-grade compression that doesn't look medical — socks you'd actually choose to put on, at the 20-30 mmHg level clinicians commonly recommend.
